Oil resistance of rubber pads
Oil resistance is a very important feature of rubber materials. In many cases, rubber pads need to be used in environments with various oily media. Oil resistance is a very important parameter of rubber pads, but various rubber materials also have oil resistance capabilities. different, which will be described in detail below
Fuel resistance: Fluoroelastomer FKM and fluorosilicone rubber FMVQ have the best resistance to fuel oil. While neoprene and chlorinated polyethylene rubber CPE has the worst fuel resistance.
The fuel resistance of NBR increases with the increase of acrylonitrile content. The fuel resistance of chlorohydrin rubber is better than that of butadiene rubber.
Mixed fuel resistance: Fluorosilicone rubber FMVQ and fluorine rubber FKM have the best resistance to mixed fuel oil. Acrylic rubber has the least resistance to mixed fuels.
The mixed fuel resistance of NBR increases with the increase of acrylonitrile content.
Fluorine rubber with high fluorine content has better stability to mixed fuel.
